(b) Number Addressing System: Every TCP/IP network requires a unique network number and every host on a TCP/IP network requires a unique IP address. The number addressing system takes care of this. A numeric or IP address comprises four numbers, each less than 256, joined together. An IP address is a 32-bit number that uniquely identifies a network interface on a machine. IP addresses are written in decimal digits, formatted as four 8-bit fields, separated by periods. Each 8-bit field represents a byte of the IP address. The byte ranges from 0 to 255. For Example: 132. 168. 1. 100
